Article Synopsis
- The study reports on the first use of the IBA Sphinx/Lynx device for daily Quality Assurance (QA) in proton and carbon ion therapies.
- Over 3 years of data collected for protons and 2 years for carbon ions focused on key QA parameters like spot size, beam range, and dose.
- The results indicate that the device effectively detects performance issues and establishes actionable tolerances, enhancing the QA process in a dual particle therapy facility.
Article Synopsis
- * It details the medical physics procedures for testing and calibrating the proton beam, highlighting methods to ensure precision in beam delivery, particularly for non-isocentric treatments.
- * Results indicate that the beam has consistently met stability and accuracy standards over two years, validating the effectiveness of non-isocentric treatment methods in routine proton therapy at MedAustron.
Purpose: To describe the implementation of dosimetry equipment and phantoms into clinical practice of light ion beam therapy facilities. This work covers not only standard dosimetry equipment such as computerized water scanners, films, 2D-array, thimble, and plane parallel ionization chambers, but also dosimetry equipment specifically devoted to the pencil beam scanning delivery technique such as water columns, scintillating screens or multilayer ionization chambers.
Method: Advanced acceptance testing procedures developed at MedAustron and complementary to the standard acceptance procedures proposed by the manufacturer are presented.
A conceptual design of a mobile isocenter carbon ion gantry was carried out in the framework of the Particle Training Network for European Radiotherapy (PARTNER) and Union of Light Ion Centres in Europe (ULICE) projects. To validate the magnets used in this gantry, Finite Element Method (FEM) simulations were performed with COMSOL multiphysics; the purpose was to evaluate the magnetic field quality and the influence of additional support structures for correctors, 90° bending dipole and quadrupoles, both in dynamic and static regimes. Due to the low ramp rates, the dynamic effects do not disturb the homogeneity and the magnetic field level.
